So I joined here today and I noticed that this project has by far the largest tasks, FLOPs-wise, the BOINC client telling me that a single one amounts to 400+ PetaFLOPs. The largest I've had thus far were on Primegrid, with I think 25+ PFLOPs for the Genefer 22 app and those took a couple of days with my GTX 1060.

The Collatz tasks take around 20 minutes to complete with the same card (1 WU per GPU), which would imply a whoopin' 350 TFLOPS, which must be a mistake; unless I've been seriously misinformed about GPU FLOPS somehow, but that'd be close to 100 times the given maximum theoretical processing speed of that GPU. My fastest FLOPS with that card so far have been 500-700 G. Yes, I know different projects and apps vary in complexity and efficiency, but this is a whole other level. Is the client's computation size of the task just incorrect? Wouldn't be the first time that the data there is seriously mistaken (ex. time remaining). There are no computation errors either and I've received credit for each task so far.

I feel like this has a really obvious answer and I'm not what you'd call an expert on these things, but please bear with me and thanks in advance.

Maybe the client is simply showing GFLOPs, when it's actually MFLOPs?

Anyone? Through optimising the config files, I'm now down to around 12-14 minutes for the 1060 and 20 minutes for an R9 270X. Still would be interesting to know the significance of the computation size given in the client.

Makes sense as this project has really bloated point values with I think CreditNew.
